EW CATARACT 37 May 2017 postoperative AL measurements and no statistical significance in between-group differences in pre- or postoperative ACD and SE, except for preoperative SE between groups 1 and 3 (P = .030). Patients with cataract achieved better best corrected distance visual acuity compared to patients with combined surgery, which was statis- tically significant (P<.05). However, there were cases of impaired postop- erative CDVA caused by age-related dry macular degeneration. After epiretinal membrane removal, eyes from study group 1 had a statisti- cally significant (P = .014) thinner central retinal thickness (CRT) com- pared to eyes of study group 2. "Several studies on phacovit- rectomy have described a mismatch between the expected postoperative refraction calculated preoperatively and the actually achieved refraction. The role of different IOL models on axial IOL movement has also been discussed controversially. In our study, a median postoperative SE of –0.88 D was obtained after phaco- vitrectomy with gas tamponade compared to –0.75 D after combined surgery without gas and –0.13 D after cataract surgery only. Com- pared with the other two groups, surgery with gas resulted in a higher median refractive PE and thus less predictable refractive results. Also, the range of the IOL power PE was higher in the gas group compared to the others. However, the mean post- operative ACD was almost identical in both phacovitrectomy groups. Although clinically relevant, none of the postoperative outcome measures were statistically significant between the study groups. To our knowledge, ours is the first study to demonstrate that IOLs with Z–haptic design applied in combined surgery result in similar magnitudes of postoper- ative PE independent of intraocu- lar gas tamponade. Also, both the combined surgery groups showed a very similar increase in depth of AC by a factor of 1.6; this means IOL implant forward movement by gas tamponade is less likely but is rather caused by combined surgery itself. It is worth noting that this study had a small number of eyes, and it was not adequately powered to detect the difference in PE, as seen by the P– values which approached clinical significance. Also, we did not assess patient compliance during the first days after surgery as body position may influence vectorial forces in- duced by gas movement," Dr. Frings said.
